Japanese Apartment Block

We came across this post and could not stop staring. No, it's not the latest Macdonald's play-land, it's a new housing complex in Tokyo designed by New York based designers Arakawa and Gin. Arakawa believes that comfort makes you grow old quick, and that residents, in particular elderly ones, need to be kept on their toes by having their interiors physically challenge them... tell that to our mother.

"Lopsided floors force the resident to maintain a good sense of balance, strangely located light switches insist we feel around for the light, whilst small veranda doors will ask you to crawl and bend to enter."

The units are $750,000, and we assume anyone putting themselves in here is up for a challenge.
